Basic HTML, CSS and JavaScript

We are looking to grow into a full time, long term relationship. Currently, our tech team of 11 have a need for a skilled front-end person to handle basic, HTML, CSS and JavaScript requests.
For example, we need to add a modal pop-up landing on any of our wiki.js webpage. The modal will have an accept or acknowledgment button which will mute the modal for 24 hours. We do not want to load any external (not included in wiki.js) JavaScript libraries but realize it might be WAY faster to do ---------- e, pretty basic. We would expect you to look up wiki.js and see how they divide the CSS and ---------- liver to us the code to insert.

This is just one of many things that seem to come up on a weekly basis. We expect to have more work in the future but for now, looking to find the right person to get to know and thrive with.
